GAS REGULATOR.

SPECIFICATION forming part of Letters `Patent No. 232,943, dated October 5, 1880.

Application filed March 3, 18S0. (Model.)

To all lwhom it may concern Be it known that I, JAMEs BLATeH 00X, of 13 Strand, Torquay, in the county otDevon, in that part ot' the United Kingdom called new and useful Improvements in Gas-Regulators for Regulating the Supply and Pressure of Gas, (for which I have obtained a patentin Great Britain, No. 3,747, bearing date September 18,1879,) of which the following is a specification. y

This invention consists ot' improvements in supply and pressure'ot' gas and for insuring at all times an equal supply and pressure to burners, gas-fires, and other similar uses, and which are meant to be fixed to service-pipes of houses, factories, or other places supplied with gas at or near their connection with the main pipes, for the purpose of preventing` alteration of pressure in the former, no matter how it may vary in the latter. They are made in various sizes, according to number of lights required to be supplied.

The apparatus consists ot' a vessel or vessels or" anyconvenient size or shape, made ot' metal, china, or glass, of metal enameled with china or glass, or ot' two or more combined, through the bottom ot' which are inserted outlet and inlet pipes. Inside this vessel, and attached to it at or near one end by a hinge or joint, is a second inverted vessel or container. Gas is prevented from escaping` between these vessels by mercury, solutions of chloride of calcium, chloride of magnesium, or other salt or salts, or glycerine, or their solutions, or any other liquid. The action is as follows: Gas is admitted through the inlet-pipe to the container, thence through the outlet-pipe to supply the necessarylights.

The mode ot' adjusting the valve is as tollows Gas being turned on,the desired pressure or iiow of gas is securedby screwing or unscrewing the balance-weight, which governs the movement ot' the container and the consequent opening or shutting ofthe valve. The nearer the balance-weight is brought to the hinge upon which the container swings the lighter and more buoyant is the latter, and the nearer the weight is brought to the opposite end ot' its screwed bar the greater the effort Patented in England September 18, 1879.

required by the gas to raise the container. When any of the lights are turned oft, or the pressure in the main is increased, gas accumulates and raises the container, stilltartherclos ing the valves, which prevents pressure at the burners which still remain lit from increasing, but preserves it at its original force.

In some cases I may use two containers connected by means ot' a pipe,and working on an axis furnished with an adj ustin g-screw and weight.

In order that my said invention may be clearly understood, I will now proceed to describe the same with reference to the annexed drawings.

Figure 1 represents a longitudinal section, and Fig. 2 a cross-section on the line IWI N.

A is a vessel, through the bottom of which pass the outlet-pipe B and inlet-pipe C. At the Lipper end of the latter is an opening, D. E is an inverted vessel or container attached to the vessel A by means of the hinge orjoint F. G is a plug attached to the container E and vfitting into the opening D, thus forming a valve. H is an air-chainber to assist in raising the container E. K is abalance ball or weight for regulating the permanent pressure required.

Line L shows the height of liquid in the v assel A; but this may be varied without in any way altering the action ot' the regulator, provided there is always a sufficiency ot' liquid to submerge the mouth of the container.

A cover is sometimes used, as shown by dotted lines, Figs. l and 2, in which case the balance ball or weight K and screw are dispensed with, and pressure is adjusted by placing small weights K on the container E. These are put on or taken off through the plug R.

S is a vent-pipe, to prevent pressure of air in the outer vessel, A.

Its action `is as follows: Gas being admitted through the pipe C and valve D G passes out thronghthepipeB to supply thelights. Should all the taps be closed the container .E will immediately riseand close the valve D G, falling again and opening the valve as the lights are lit. The pressure ot gas at the burners is regulated by screwing forward or back the ball or weight K, or by putting on or taking ott' the equivalent weights K', and once fixed IOC no variationean take place unless the regulating-ball K or Weights K be again purposely moved.

The air-chamber H may be dispensed with by enlarging the container E.

Fig. 3 represents a longitudinal section of regulator, specially planned for use Where mercury is preferred as a means of sea-ling the joint between the outer and inner vessel. A is the trough for containing mercury; I3, outlet-pipe; G, inlet-pipe; I),container; E, plug, which, fitting into end of pipe C, forms valve; F, ball or Weight to balance container D and adjust pressure; H, hinge or joint line; L, height of mercury. Fig. 4L represents a crosssection of same through the line O I. Fig. 5 represents a modiiication of the-valve G.

I am aware of the American Patent No.

12,943 and of British Patent No. 2,527 of 1858, and I hereby disclaim lthe construction zo therein shown and described.

What I do claim is- In a gas-regulator, the combination, with the outer vessel for holding a sealing-liquid and having the inlet and outlet pipes arranged as 2 5 shown, ofthe inverted gravitating vessel p'iv: oted at one end inside the outer vessel, and provided with an adjustable Weight, said inverted vessel having on the inner surface of one ot' its Walls a rigidly-fixed valve, all of said 3o
